the wheel 10 will not rotate readily, it will rotate when a sufficient force is applied thereto.

Let it be supposed that the door 2 is closed as shown in Figure 2, the parts'of the device being arranged as depicted in Figure 3, the rear bar 16 of the slide being engaged with the toothed wheel 1O. When the door is swung to an open position, the slide 15 is retained at first by the catch 38, the parts 17 of the slide moving in the openings 21 which are formed in the ears 9 and 12, and in the door 2. The nose 23 on the member 19 of the slide enters ber tween the rollers 3.8 on the arms 31 and82 of the shafts 25 and 26, the shafts being rotated, and the wings 27 swinging outwardly, away from the door, until the wlngs come together, the rollers riding on the cam edges 22. The wings 27 are foraminous, and air can pass through them readily. The result is that the flies on the wings are held on the wings,,and are crushed between the shaft 25 engages the arm 32 on the shaft 26 and carries the shaft 26 forwardly at its upper end, away from the door, the shafts 25 and 26 moving outwardly in the slots 29. Owing to the fact that the arms 31 and 32 are crossed, as shown at 38, the aforesaid movement of the shafts is necessary in order that the wings 27 may come together and crush the flies. Further, because the shafts are swung outwardly as aforesaid,

the springs 37 are put under additional tension and are rendered pecullarly efficient for closing the wings 27 against the door 2 as hereinafter explained, the wings closing so quickly against the door that flies cannot light either on the door or on the inner surfaces of the wings. The flies light on the outer surfaces of the wings, when the wings are in the position shown in Figure 1. and, consequently, the flies are crushed between the wings, when the wings come together.

The end of the nose 23 on the bar 19 ultiina tely comes into contact with the upstands ing portion of the upper bearing 28, and, then, the slide 15 moves forwardly for an instant with the door 2, the wheel 40 be ing rotated and the rear bar 16 of the slide being detached from the wheel. Thereupon the springs 37 react, and cause the shafts 25 to be rotated, the shafts moving back wardly in the slots 29, into parallelism with the door 2, and the wings being closed against the door. When the shafts 25 and 26 are rotated by the springs 37, as aforesaid, the arms 31 and 32 on the shafts swing into the position shown in Figure 3, the rollers 35 riding toward each other on the cam edges 22 of thebar 19 of the slide 15 and advancing the slide into the position shown in Figure 3.

lVhen the door 2 is swung to a closed position, the rear bar 16 of the slide 15 rides over one of the teeth of the wheel 40, and engages with the said tooth, and slide 15 tilting vertically on the door 2 and on the ears 9 and 12, to permit the rear bar 16 to engage with the said tooth of the wheel 40, it being observed, referring to Figure 7, that the openings 21 in the ears 9 and 12 and in the door 2 are large enough to receive the side pieces 17 of the slide 15 somewhat" loosely.

A hook 7 2 or like retainer, is pivoted on the door 2, and is adapted to be engaged with the rear bar of the slide 15, as shown frame; a door hinged to the frame; panels mounted to swing on the door; a member movable on thedoor; means for connecting said member operatively with the panelsto swing the panels away from the door and togetl'ier when the door is opened and when said member is held against movement with the door; means on the frame for holding said member against movement with ,the door when the door is opened,:the holding means being automatically releasable from said member after the door has been opened a predetermined amount; and spring means for swinging the panels toward the door and for advancing the movable member with respect to the door after. said member has been released from the holding means.
